Infact I don't think i've ever read anything bad about their staff, except for the management.
There been abundant postings on the GSM threads, including mine, laying the blame for the poor service quality on management, not the staff. A fish rots from the head.
It is a fact of life that people are always more vocal about bad experiences than good ones, which is why a bad airline will appear to be significantly worse than its mediocre competitors. GSM was a bad airline by many criteria.
